Product Introduction:

The high-performance hollow micro-bubbles/microspheres supplied by Zhongke Yaki, a new type of high-performance lightweight material, are widely applied in recent years. It is a kind of inorganic non-metallic powder with hollow vacuum spherical shape, will be the main direction for new type composite in the 21st century. Its true density is 0.15 to 0.60 g/cm3, particle size is 5-180µm. Due to its excellent advantage of light weight, large volume, lower thermal conductivity, high crush strength, fine dispersion and good flowability, and excellent chemical stability, etc.,  it can be widely used in aerospace, buoyancy in deep-sea submersibles, paint coating, lightweight insulation board, plastic, glass reinforced plastics, artificial stone, putty, sports equipment, automobile, emulsion explosive, low density slurry and drilling fluid.

Storage and handling: To minimize the potential for “caking” and prolong the shelf life, please keep the product in the dry and unheated warehouse in unopened cartons. Don’t leave the product in the damp. Carefully re-tie open bags after use. If the PE bag is punctured during shipping or handling, use this bag as soon as possible, patch the hole, or insert the contents into an undamaged bag.
